OMRON BF511 vs Tanita BC-418MA
OMRON BF511 and Tanita BC-418MA: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
OMRON BF511: when to consider it
BF511 is a scale with eight sensors contacting hands and feet. It uses 50 kHz BIA to estimate body-fat percentage, skeletal-muscle percentage and visceral-fat level alongside weight and BMI. It provides a whole-body overview; separate limb results are not documented.
Tanita BC-418MA: when to consider it
BC-418MA is a segmental body-composition analyser. An academic facility’s instrument description lists weight, body fat, fat-free mass and regional outputs. Check the exact device designation, including MA, when booking.

Highlighted rows differ. Unknown values stay unknown.
| Specifications | OMRON BF511 | Tanita BC-418MA |
|---|---|---|
| Method | Bioelectrical impedance (BIA) | Bioelectrical impedance (BIA) |
| Measurement frequencies | 50 kHz | Not verified |
| Electrodes | 8 hand-and-foot sensors | Not verified |
| Maximum weight | 150 kg | Not verified |
| Documented outputs | Weight, BMI, fat and skeletal-muscle percentage, visceral-fat level | Weight, body fat, fat-free mass; regional results |
| Designation scope | Not verified | BC-418MA |
Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.
